When Sarah Coleman and Carl Sack first saw “Big Blue,” they knew they were home. The massive house, so named because all the rooms were painted shades of the color, was built in the 1920s on two and a half lots in the Corey-Merrill neighborhood of inner-city Denver.

Below is the post that originally was put up on Mapawatt on the Utility Green Button. As the Green Button is adopted by more and more utilities, I believe Home Energy Pros should make sure to inform every customer of its existence and how it can help homeowners better manage utility bills.

The idea for the utility Green Button was first put forth by U.S. CTO Aneesh…

Why is it so hard to care about snakes? Or the desert? The climate? And especially the environment more generally?

This time the snake was real. Right there on the side of the road. Some evenings ago, however, in the waning hours of twilight, it turned out to be just a short length of black rubber hose that was also laying…

Tom posted the 5 "disadvantages" listed below. I did not agree with the list so I thought I would post them as Tom did and then add my comments below each one. Be sure and join the discussion by posting…

The Energy Audit is Complete: The Homeowner Chooses These Energy Saving Improvements

Now that the 5 year old has put down the foam dart gun and stopped crawling in and out of the blower door, it's time to make some energy saving recommendations to the homeowner. After completing an energy audit of the home, it is usually fairly easy to start the conversation with the owners on what they should…

“All politics is local.” This quote from the late US Congressman Tip O’Neill continues to frame political strategies today. It turns out his premise also applies to environmentalism. All sustainability is local, as a Massachusetts software company reveals in a new application that takes on the complicated task of quantifying the green efforts of corporations.

These are the latest ideas and bills in congress, which may or may not actually happen.

First up are new tax credits for homeowners investing in energy efficiency upgrades. The Cut Energy Bills at Home Act.

It's based on annual predicted energy cost savings from heating, cooling, hot water and “permanent lighting” in a primary residence. For a minimum credit of $2,000, homes would need to reduce energy costs by 20 percent. Incremental credits are…

US Congresswoman Michele Bachmann often asks why government should tell us which kind of light bulb to choose. Turns out it’s a question with a trillion dollar answer.

We will save $1.1 trillion through 2035 because of existing energy efficiency mandates for light bulbs and appliances, according to a report issued this week by the American Council for an Energy-Efficient…

You woke up this morning full of vim and vigor, ready to tackle the world of home energy efficiency. Of course, your first dreamy thoughts were: is this major solar flare going to knockout electricity in the midwest power grid, and then, if Fermilab has found proof of the Higgs Boson, will I be able to fully explain the phenomena of convection and chimney effect to people? After your morning coffee, the reality check sets…

The US economy is three times larger than China’s, yet when it comes to developing a clean energy industry, China keeps besting us. The US came in second – again – to China this quarter in Ernst & Young’s much-watched …

Fuel poverty, that is to say people who can't afford to heat their homes, is at all time high levels in the U.S., Canada, and the U.K. It causes at times a terrible human condition, death, which is estimated as 8,000 people per year in the U.K. There have been calls for immediate "super energy efficiency." No doubt the rest of the world is affected, also.

Heating oil prices in the U.S. are topping $4.11/gal(up), propane $2.90/gal(up), natural gas…

Why is there a heating register 4 feet up on the wall?

In my last article, I spoke about a home energy audit and the hot tub on the back deck. Remember, it was a manufactured home with a great deck overlooking a roaring hillside stream. Next door, the neighbors were the countryside recyclers, at least I suppose that's what they might call themselves.
